Reconstruction and intensification of existing WWTPs

Reconstruction and intensification of existing WWTPs

Deteriorated cleaning efficiency, few dysfunctional parts, or insufficient capacity of your wastewater treatment plant may not be the reason why you need to set up a brand new WWTP. Many existing wastewater treatment plants which can no longer perform at 100% can continue to function without difficulties if you let them refresh or intensify over time.

Our effort is to apply the latest knowledge of science, scientific and technological development in all projects of reconstruction and intensification of existing WWTPs so that all the capacities of an existing WWTP are used as economically as possible. In addition, Hydrotech is able to provide the reconstruction or intensification of existing WWTPs in full operation so you will not have to interrupt or limit production.

Sedimentation tank reconstruction in wastewater treatment process

Reconstruction of the settling tank at the WWTP of our customer from petrochemical industry will take place in the next months. Well-functioning sedimentation is one of the key processes for any wastewater treatment plant. This is mainly due to its location, usually as the last stage of process. The project involves minor civil work modifications and installation of a completely new sludge raking device at the bottom of the settling tank.

Increasing of oxygen concentration in the WWTP´s tanks

Hydrotech was awarded with a new project for the reconstruction of a part of a wastewater treatment plant. This is among the most substantial sections of the WWTP and ensures air supply to the biological part. Planned works include aeration system and air distribution pipeline replacement, supply of new blowers with a control program constantly measuring dissolved oxygen concentration in the aerobic tanks. Sufficient oxygen concentration in the system is a necessary condition to ensure sufficient elimination of pollution from wastewater.

Dairy factory, waste water and sludge treatment

A new sludge dewatering device for waste sludge produced at local wastewater treatment plant in dairy factory in Moravian region, Czech Republic was installed. It is a slow-running screw press that also pumps sludge with low concentrations and therefore directly from the tanks. This process efficiency depends on sludge quality entering the technology. Manufacturer declares the ability to achieve a dry matter output concentration from 15 to 30 %. In some cases, this type of dewatering technology costs significantly less than conventional technologies, e.g. centrifuges.
